With the louvers in this position, reverse rotation of the knob 60 will of course effect a reverse movement of the parts and the louvers will be opened as shown in Figure 4. If desired, a face plate 61 may be secured upon the forward face of the stile of the frame 1 through which the eccentric spindle 58 extends, and may have arrows G2 stamped or otherwise marked thereon to indicate the direction the knob 60 is to be turned in either opening or closing the ventilator.

H ving thus described the invention, what is claimed as new is:

1. in a ventilatin device of the class described, a frame, swinging louvers mounted in the frame, a slide mounted in the frame and guided thereby for movement in a rectilinear path, operative connections between the slide and the louvers, the slide having an abutment portion across its end, a manualiy operated guiding element, and an eccentric mounted on said element and arranged to ride slide.

2. In a ventilating device of the class described, a frame, swinging louvers mounted in the frame, a slide mounted in the frame and guided thereby for movement in a rectilinear path and having vertically spaced transverse abutment portions, operative connections bet veen the said slide and the louvers a manualiy oaerable spindle mounted in the frame, and an eccentric secured upon the inner end of the spindle parallel with the face of the slide and operating between and engaging the saiu abutment portions of the slide.

in a ventilating deviceof the class described, a frame, bracket members secured within the frame and having overlapping apertured end portions, a guide rod fitting through the apertures in said overlapping portions of the brackets, a slide mounted within the frame between said brackets and guided by said rod and a wall of the frame, swinging louvers mounted in the frame and operativcly connected with the slide, and means for adjusting the slide.

a. In a ventilating device of the class described, a frame having an internal flange provided. with an arcuate slot, swinging louvers mounted within the frame, a stud proj ecting through the arcuate slot in the flange upon the abutment portion of the thus parallel with the face of the slide.

of the frame and connected with the louvers, a slide; mounted within the frame, a link pivotally connected at one end to the slide and at its opposite endto said stud, and means for moving the slide.

5. In a ventilating device of the class de scribed, a frame having an opening therethrough and comprising assembled front and rear sections, the rear section having an inwardly and downwardly inclined flange to overlap the downwardly inclined flange on the rear section of the frame when the louvers are closed and one of the flanges upon the lowermost louver being arranged to underlap the upwardly inclined flange on the front section of the frame when the louvers are closed, the oppositely extending flanges of adjacent louvers being arranged to mutually overlap in closed position of the louvers, and means for simultaneously adjusting all the louvers.

6. In a ventilator, a frame having an opening therethrough and consisting of front and back sections, inwardly extending projections on the sections, means for connecting said projections to detachably secure the sections together, inwardly projecting flanges on the side portions of the back section spaced from the inner side edges of the section, an inwardly projecting flange on the back section along the upper side'of the opening therethrough, an inwardly projecting flange on the front section along the lower side of the opening therethrough, a plurality of louvers pivoted at their back ends to the inwardly projecting flanges on the side portions of the back section, there bein oppositely extending flanges along the front and rear edges of the louvers at'obtuse angles thereto, the flanges at the rear edges of the louvers abutting the inner side edge portion of the back section in open position of the louvers to limit the movement of the louvers and said flanges, in closed position of the louvers, underlapping the flanges at the upper edges of adjacent louvers and the inwardly projecting flange on the front section of the frame respectively with the upper flange on the uppermost louver overlapping the inwardly projecting flange on the back section of the frame along the upper side of the opening therethrough, and rail pivoted to and connecting the front ends of the louvers.

7. In a ventilator, a frame having an CIT the aback section, and rails arranged adjacent the front edge of the =louvers at the ends thereof and consisting of front Webs and spaced flanges projecting rearwardly from said webs with theztermninlportions 0f the inn'er flanges extending laterally to abut the outer "flanges, the front e'd g'esofthe louvers being pivoted to said inner flanges.
